Fiber optic cables exhibit superior immunity to electromagnetic interference and environmental degradation compared to copper cables.

Because fiber optics transmit light rather than electrical signals, they are not susceptible to electromagnetic interference (EMI) from nearby electrical equipment, fluorescent lights, or industrial motors. This makes them more reliable in harsh environments and over long distances, where copper cables suffer signal degradation and noise. Additionally, fiber’s glass composition allows it to endure temperature fluctuations and even submersion in water without loss of performance.
